Charging port detective

The questions

1. Question 1 of 6The plug feels loose and sits slightly proud. What is the classic cause?

   • A software bug
   • Pocket lint packed at the back of the port
   • A weak battery
   • The wrong language setting

   Show answer

   Answer: Pocket lint packed at the back of the port

   A grey felt layer of lint at the back of the port stops the plug going all the way in. Turn the phone off and look inside with a torch, as Samsung's steps begin.

   • A torch
   • A different cable

   Answer: Compressed air, cotton swabs or paper towels

   Apple says don't use compressed air and don't put objects such as a cotton swab or paper towel into the port. Tap it gently port-down against your palm; if lint is packed in, take it to Apple or an authorised repair shop.

6. Question 6 of 6Wireless charging works, but every cable fails. What does that tell you?

   • The battery is dead

   • The charger is too new
   • Nothing

   Show answer

   Answer: The port is the problem: time for a repair

   If wireless works and every cable and charger fails, the port is the problem. Book a repair, and keep going on a wireless charger meanwhile if your phone supports it.
